Question regarding invalid symbol problem

[ksengkit]

So i was trying to set up a relation for my creo file and there is a problem that keeps persist. It is known as invalid symbol. Attached below is a screenshot of the problem. Would appreciate if anyone could explain to me what's wrong or help me with this

‌It is treating TURNS as a function. You need to have a * between TURNS and WAVES for multiplication. As you have it written WAVES would be used as a variable and TURNS would return a value similar to the cos() function.

Kevin is correct. Rewrite your formula to say the following: sd5 = ((height/turns)-sd4)/2)*cos(trajpar*360*turns*waves

Hi,

as Kevin mentioned Creo tells you that turns() is unknown function.
